I must add that the keyholes are hidden and one has to perform a few manoevres to see them.
To expose the first one (A) one must press the small button ( 1).
To expose the second one ( B) one has to press the small rivet ( 2 ).
To expose the third one (C) one has to push a small pin or thin nail into a hole ( 3).
Nobody knows if the safe is locked with one, two or three locks, if he locks are working or rusted, and if one has to unlock them in any particular order, etc.
